Water Supply in Medavakkam: CMWSSB Piped Water & Groundwater Status

Water Supply in Medavakkam: CMWSSB Piped Water & Groundwater Status is one of the most important things to check if you are buying or renting a home near Chennai’s busy Velachery–Tambaram and Medavakkam–Sholinganallur roads. Right now, Medavakkam gets water from a few different sources. Most houses use borewell water (dug 120 to 700 feet deep), local Panchayat water tanks, and private water tankers. At the same time, the government is laying pipes to bring Chennai Metro Water (CMWSSB) and treated sea water from the Nemmeli plant. Because Medavakkam sits right on the border of the St. Thomas Mount Panchayat and the Greater Chennai Corporation (Zone 14 / Perungudi and Sholinganallur), water supply changes from street to street. That is why checking the water setup—or buying a flat in a big, well-planned community like Prestige Falcon City Chennai—is very important before you buy a house or land.

Why Water Infrastructure Drives Medavakkam Real Estate

Medavakkam has changed from a quiet town into a popular housing area that connects Old Mahabalipuram Road (OMR), Sholinganallur, Velachery, and Chromepet. With the new Medavakkam flyovers open and new Metro train stations coming up just 5 minutes away, many new apartment buildings and plots are being built fast.

Current Status of CMWSSB Piped Water in Medavakkam

To understand piped water in Medavakkam, you need to know who takes care of the area. Unlike central Chennai, which has had Metro Water for many years, Medavakkam is a Village Panchayat under the St. Thomas Mount Panchayat Union. It sits right between Greater Chennai Corporation (GCC) Zone 14 (Perungudi, Pallikaranai, and Sholinganallur) on one side and Tambaram Corporation on the other.

1. Local Panchayat Supply vs. CMWSSB Integration

• Panchayat Piped Network: Most streets in Medavakkam get piped water from the local Panchayat. This water is stored in big Overhead Tanks (OHTs) filled by deep borewells and government water lines. The Panchayat sends this water to homes once every two or three days for washing and daily use.
• CMWSSB Expansion & Ring Main Projects: CMWSSB is now laying big water pipes in South Chennai to bring water from the Nemmeli plant and Chembarambakkam lake. Main roads like the Medavakkam–Sholinganallur Road and areas near Perungudi are getting connected to the Chennai Metro Water network step by step.
• Dial-a-Tanker Services: People living on streets that do not have working CMWSSB pipes yet can book government water lorries (6,000 to 9,000 liters) online, or buy water from private tankers during the hot summer months (April to June).

2. Standalone Buildings vs. Large Gated Townships

Small apartment buildings (with 6 to 12 flats) usually have small underground tanks and find it hard to get water tankers on time in summer. On the other hand, big gated communities build strong water setups. They have huge underground water tanks, many deep borewells, water cleaning plants, and regular tanker agreements so families never run out of water.

Groundwater Status in Medavakkam: Depth, Yield & TDS Levels

The ground under Medavakkam has hard rock in some places and soft clay near its big lakes—namely the Medavakkam Periya Eri (Big Lake), Sithalapakkam Lake, and Perumbakkam Lake.

Key Groundwater Insights for Homebuyers:

• Hard Rock Geology: Because most of the Tambaram–Medavakkam belt has hard rock under the soil, shallow open wells dry up fast in April and May. New apartment buildings dig deep borewells between 300 and 700 feet to get steady water from deep inside the rocks.
• Water Quality & Hardness: While CMWSSB piped water is soft with low salt (TDS of 250 to 350 ppm), raw borewell water in Medavakkam has a TDS level between 500 and 1,200 ppm. Using a home RO water purifier for drinking and a building water softener plant keeps your vessels, bathroom taps, and hair safe from salt water.
• Impact of Lake Restoration: Cleaning and deepening the Medavakkam and Perumbakkam lakes has helped rainwater go deep into the soil. Because of this, underground water levels come up quickly after the rainy season (October to December).

Prestige Falcon City Chennai: Solving Medavakkam’s Water & Utility Needs

For homebuyers who want to live in Medavakkam near IT companies without worrying about borewell repairs, salt water stains, or summer water shortages, Prestige Falcon City Chennai gives an easy, worry-free water setup.

Located on the main Medavakkam–Sholinganallur Road (PIN 600100), just 5 minutes from ELCOT SEZ and the upcoming Medavakkam Metro Station, Prestige Falcon City Chennai is a huge 23-acre gated community built by the Prestige Group. It has 2,170 luxury flats (2, 3, and 4 BHK) across 22 tall towers (2B+G+14 floors).

How Prestige Falcon City Chennai Ensures 24/7 Water Security:

• 80% Open Space for Massive Groundwater Recharge: Unlike small buildings that cover most of the land with cement, Prestige Falcon City Chennai keeps 80% of its 23 acres as open green land, parks, and gardens. When it rains, this big open ground lets rainwater soak easily into the earth through Rainwater Harvesting (RWH) pits, keeping the borewells full all year.
• Centralized Water Treatment Plant (WTP): All borewell and tanker water passes through a big Water Treatment Plant before going to the overhead tanks. This cleans and softens the water so families get clean, soft water in every kitchen and bathroom tap.
• Zero-Discharge Sewage Treatment Plant (STP) & Dual Plumbing: A lot of daily home water goes into flushing toilets and watering plants. The project has a modern Sewage Treatment Plant (STP) that cleans used water and sends it back for toilet flushing and the 23-acre garden. This saves up to 40% of fresh underground water.
• High-Capacity Underground Sumps & Smart Metering: Huge underground water tanks store enough water for many days. With 100% power backup for water motors, lifts, and common areas, families get non-stop water in their taps even in peak summer.

Practical Checklist for Property Buyers & Tenants in Medavakkam

When you visit a flat, house, or plot in Medavakkam, check these four easy things:

1. Inspect the Water Treatment Plant (WTP): In gated apartments, ask the manager if the building has a water filter and softener plant to clean the borewell water.
2. Check Open-to-Built Space Ratio: Projects with more open green space (like the 80% open land in Prestige Falcon City Chennai) save huge amounts of rainwater every rainy season compared to tight, crowded buildings.
3. Verify Borewell Count & Yield: Make sure smaller buildings have at least two working borewells dug at different depths (one shallow well and one deep borewell below 450 feet).
4. Confirm Dual-Plumbing & STP Recycling: Big apartment communities that reuse cleaned water for toilets and gardens buy far fewer water tankers in summer, which keeps your monthly maintenance bill low.
